Chapter 22, Problem 40

A generator uses a coil that has 160 turns and a 0.71-T
magneticfield. The frequency of this generator is 60.0 Hz, and its
emf hasan rms value of 120 V. Assuming that each turn of the coil
is asquare (an approximation), determine the length of the wire
fromwhich the coil is made.
